The hyoid bone is a floating bone. It is the only bone in the body that does not form a joint with any other bone. A small U-shaped bone located at the level of the third cervical vertebra C3 found just inferior to the mandible. The hyoids’ function is to help hold the trachea open while inhaling and form a bony connection for many muscles contributing to mastication, swallowing the tongue muscles. From the temporal bone, ligaments and muscles grow down and connect to the hyoid bone, suspending it in the skull. Likewise, the organ system is suspended from the Hyoid.
